Chris Froome produced a stunning performance on stage 16 of the Vuelta a Espana to almost double his lead in the general classification.
Only one rider got within 57 seconds of the Team Sky man in Tuesday's individual time trial, as Froome's GC lead over Vincenzo Nibali stretched to one minute and 58 seconds.
The Team Sky rider completed the 40.2-kilometre route in 47 minutes, with Wilco Kelderman 29 seconds slower in second to leapfrog Ilnur Zakarin into third overall.
Nibali finished third, three seconds short of a minute off Froome's time, and the Briton now looks well on course to complete a Tour de France and Vuelta double, becoming only the third man to do so.
The victory is Froome's second of this year's Vuelta, having also triumphed on stage nine atop the steep finish at La Cumbre del Sol.
Despite the emphatic nature of the win, Team Sky boss Dave Brailsford played down its significance.
"No surprises, everybody was pretty much where you expect to them be," he said. "We can tick that one off, turn the page and get back into the steep hills.
"It will be interesting, a lot of the guys didn't go full in the time trial, so it will be interesting to see how they go."
GOOD DAY/BAD DAY
Only one man can lay claim to Tuesday's 'Good Day' honour and that is Froome following a peerless ride from Circuito de Navarra to Logrono.
And while Nibali may initially have been pleased with a ride that provisionally placed him second for the day behind Kelderman, the sight of Froome's clock stopping at 47 minutes will have given him a sinking feeling.

Next up for the riders is a gruelling 108.5km mountain stage from Villadiego that finishes atop Los Machucos - a climb Froome described as "a wall" after his win on Tuesday. The Briton will hope to neutralise any attacks on that climb as the Vuelta begins its final approach to Madrid.
